Hello Friend, Good that you are seeking a help. All your symptoms are pointing toward stress and anxiety. It's not adviced to hold  on such mental disturbance within you for long as it will create negativity and health issues. Better to ventilate with someone you care about you. No worries. These are just like any other physical illness and can be treated through counseling session and few lifestyle changes or therapies. Take a professional counselling support first to assess yourself and figure out what is causing such emotional imbalance and suitable solutions.

U need to consult a psychiatrist it can be treated through medications and psychotherapy. Seek help of professional as early as possible.
